I never tried with mpg123. But I just diff the 2 sets of patches, and 
the only difference I can see is that the one on linux4sam doesn't 
handle full duplex, whereas the one I posted on the alsa mailing does...

Yoy can find enclosed both files, may I ask you to test with both?
If it fails then I guess there is something wrong with the way the full 
duplex is done(even though I have tested it on my board...)

Regards,
Sedji
